Well, if it helps you feel better... I'm half-Italian, and I don't get bitter about people wearing togas. I don't even get bitter about SEXY togas; Roman women lived in a shittily patriarchal world, and personally, I think it's awesome that women today are able to live more a more liberated existence. :D
(Although, I will say: I believe togas were technically the name of a garment worn primarily by men. Women wore something called a stola. I skipped this detail in the story so I wouldn't lose people on the historical minutiae though.)
Then there's the fact that the Roman empire was so relentless in its colonization efforts that there are very few people in the Western world today who aren't descended from ancient Romans, whether they're Italian or not...
Anyway, Italian heritage occupies a weird sort of cultural space in the US, which is a whole other essay in itself. It's only recently that Italians came to be considered "white," and even then, not by everyone... which means that the structural/institutional disadvantages are still very much felt in a lot of families of Italian descent, despite the new "white" status. There are lots of anti-Italian prejudices and stereotypes that simply go unquestioned by the larger culture too. So it's complicated.
That said, I definitely appreciate when non-Italian people actually recognize that they're playing with elements of Italian culture: using tarot cards (which, as far as I'm aware, are historically attributed to Italy), putting Italian dishes on their menus, etc. So thank you for being as mindful as you are! 💜
